It's a soft metal that is silvery in color when pure. It's also very lustrous, or shiny. Yttrium is a good conductor of electricity and heat, and it's easy to mold into different shapes.

Also, Is yttrium Reactive or nonreactive?

Yttrium is a highly crystalline iron-gray, rare-earth metal. Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids.

Besides, What are the properties of yttrium?. Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3.

Similarly, What are three uses for yttrium?

Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation. Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals.

What can destroy yttrium?

Water reacts with yttrium and its compounds to create hydrogen gas and Y2O3. Concentrated nitric and hydrofluoric acids do not rapidly destroy yttrium, but other stronger acids do.

What elements are named after scientists?

Many elements were named after famous scientists. Some of the best-known elements include einsteinium (Albert Einstein), curium (Marie and Pierre Curie), rutherfordium (Ernest Rutherford), nobelium (Alfred Nobel), and mendelevium (Dmitri Mendeleev).

Who created curium?

Curium was first made by the team of Glenn Seaborg, Ralph James, and Albert Ghiorso in 1944, using the cyclotron at Berkeley, California. They bombarded a piece of the newly discovered element plutonium (isotope 239) with alpha-particles.

Is yttrium toxic to humans?

Water soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. In experiments on animals, yttrium and its compounds caused lung and liver damage. ... Exposure to yttrium compounds in humans may cause lung disease.

What is an interesting fact about yttrium?

Yttrium (Y) has an atomic number of thirty-nine. This rare-earth element ignites easily in air, and has been found in rocks retrieved from the moon. Interesting Yttrium Facts: In 1794, Johann Gadolin isolated yttrium in the mineral ytterbite.

Is yttrium a rare earth element?

Rare earth elements (REEs) are a group of 15 elements referred to as the lanthanide series in the periodic table of elements. Scandium and yttrium, while not true REEs, are also included in this categorization because they exhibit similar properties to the lanthanides and are found in the same ore bodies.

Is yttrium a physical property?

Physical properties

Yttrium has a bright, silvery surface, like most other metals. It is also prepared as a dark gray to black powder with little shine. Yttrium has a melting point of 1,509°C (2,748°F) and a boiling point of about 3,000°C (5,400 F). Its density is 4.47 grams per cubic centimeter.

How common is yttrium?

Abundance. Yttrium is found in most rare-earth minerals, it is found in some uranium ores, but is never found in the Earth's crust as a free element. About 31 ppm of the Earth's crust is yttrium, making it the 28th most abundant element, 400 times more common than silver.

Why are alkali metals so reactive?

All the alkali metals—lithium, sodium, potassium, and so on—have only one electron in their valence shell. Because this one electron is likely to be far from the nucleus, it feels little attraction to the atom. The result: Alkali metals tend to lose this electron when they participate in reactions.

What is the symbol of uranium?

Uranium- is a silver-fray metallic chemical element. Uranium is in the periodic table that has a symbol U and atomic number 92. It also has the highest atomic weight of the naturally occurring elements.

What happens when yttrium reacts with oxygen?

Oxygen forms 2- ions by gaining 2 electrons. Therefore, 2 yttrium atoms transfer 6 electrons to 3 oxygen atoms, making two yttrium 3+ ions and three oxide (2-) ions and thus the formula of yttrium oxide is Y2O3 .

Can yttrium be found on the moon?

Yttrium can be found in most of the rare earth minerals, but has never been discovered in the Earth's crust as a freestanding element. Lunar rocks gathered during the Apollo moon missions contain yttrium. The human body also contains yttrium in tiny amounts, usually concentrated in the liver, kidneys, and bones.

What does yttrium cost?

Yttrium is currently worth $3,400 per pound, europium costs $20,000 per 100 grams and terbium sells for $1,800 per 100 grams. Dysprosium, the cheapest of the rare-earth elements discovered, only costs $450 per 100 grams.

What are the coolest elements?

The most weird and wonderful elements in the periodic table
  • Krypton (Atomic number: 36)
  • Curium (Atomic number: 96)
  • Antimony (Atomic number: 51)
  • Copernicium (Atomic number: 112)
  • Bismuth (Atomic number: 83)

Are lanthanides safe?

In recent years, however, some scientists have questioned lanthanides' safety. In matters concerning health care, for example, some MRI patients have attributed a litany of side effects, including long-term kidney damage, to their exposure to the lanthanide gadolinium, a commonly used MRI contrast agent.

Is rare earth toxic?

Securing just one ton of rare earth elements produces 2,000 tons of toxic waste, and has devastated large regions of China, said Günther Hilpert, Head of the Asia Research Division of the German think tank SWP.

Which is the rarest element on the Earth?

A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.

Is Curium man made?

Curium does not occur naturally; it is typically produced artificially in nuclear reactors through successive neutron captures by plutonium and americium isotopes. Curium is very radioactive, more electropositive than Aluminum, chenically reactive. A few compounds of curium are known, as the fluorides.

Does curium glow in the dark?

Curium is a dense and hard transuranic element that is silvery-white in appearance. ... Curium is the most radioactive element that can be isolated. It is so intensely radioactive that it boils water, making its chemistry difficult to study. It also glows in the dark (see right).
